MACHINERY 0R APPARATUS T0 BEUSED IN THE MANUFACTURE OF PAPER, WOOD PHLP, AND OTHER KINDRED INDUSTRIES. e

SPECIFICATION forming part of Letters Patent No. 276,989,-dated May 1, 1883.

Application filed January 11, 18 83. (No model.)

To all, whom it mag/ concern:

; Be itknown that we, FREDERIGKWRIGLEYI i and JAMES ROBERTSON, citizens of the United Kingdom of Great Britain and Ireland, residing at Bury, in the county of Lancaster, England, have invented certain new and useful Improvements in Machinery or. Apparatus Used in the Manufacture of Paper, Wood Pulp,

and other Kindred Industries; and we do it appertains tomake and use the same, reference beinghad to the accompanying drawings, and to theletters' and figures ofireference marked thereon, whichform a partof this specireference to the section or class of such appa- ,Onrinvention, whichyrelates to machinery ratus known as the fjog knotter or strainer; andour invention has for one of its objects to render the movement or action of the said knotter or strainerequal over all its surface,

, 1, whereby the slits are prevented from filling up i and the knotter or strainer plates'are worn evenly and equally, and therefore pass a larger 1 quantity of pulp in relation to'the gage of,

plate or sieve used.

lOurinvention has also for its object to extractsurplus water from the pulp after it has been strained and before it reaches the papermaking-machine wires, thereby lessening the tear and wear on the said wires and causing them tolast much longer.

, And in order that our said invention may be properly understood, we now proceed more particularly to describe the system, mode, or manner in or under which it is or may be used or carried out in practice, reference being had to the annexed drawings, and to the letters and figures marked thereon-that is to say:

On the sheetof drawings hereunto appended, Figure 1 is a longitudinal section, and Fig. 2

y a transverse section, of the improved jog knotter or strainer constructed in accordance with our" said invention; and, as shown-bythese figures, the improved knotter or strainer con- Patented in England November 1, 1882, No. 5,201.

mover; or, instead of the stepped tappets or camsE, eccentrics, cranks, or otherequivalents may be used: This action may be communicated also from a shaft or shafts workingeither above or below or at the side of the strainer; but we prefer the arrangement as shown on the drawing's and stated above, the principle being the same in all-that is to say, the rapid and simultaneous perpendicular jog or action given t to the whole surface of the knotter or strainer. or apparatus used in the manufacture of paper, wood pulp, and other kindred industries, has

the shaft D passes. a The boxes Grand thepipe ortube H thus form one continuous chamber containing theprincipal moving parts of the apparatus; and as the chamber isfilled with oil, tar, or other equivalent lubricant, preferably to the level of the covers I of the boxes G,

the friction, tear, and wear on these parts are reduced to a minimum.

The strainer-plate frame B is supported by vertical rods J, whose lower ends are in conframe is attached to the vertical rods J, are

each formed with a slot, as indicated at 0,.Fig. 2, so that on withdrawing the cotters or keys b the frame may be tilted or raised up in the I usual manner. When in the position shown on the drawings the frame B may'fall on or jog against pads fixed to the flange of the vat A underneath the horns or brackets N; or, and as is preferred, it may drop upon the upper ends of the two top guides, Lyand the amount of jog given to the said knotter or strainerplate frame is regulated bywedges P, on which the boxes G are carried. The wedges P are capable of being moved in a horizontal plane by the screws (7, and when the jog has been regulated they are securely fixed in position by the screw-bolts 0.

By constructing and operating thejog knotter or strainer substantially as hcreinbefore described the whole surface of the strainerplates is available for straining the pulp, the tear and wear on the moving parts are reduced to a minimum, and the apparatus is practically noiseless.

Our improved mode of action, as hereinbefore described, also permits of an increase in the number ot'jogs per minute far in excess of anything hitherto produced, each jog still bein g distinct and separate. Therefore, as each distinctjog passes a certain quantity of stuff, it naturally follows that the efficacy of the strainer relatively to the area of the plates or sieves employed is increased, and the space required for strainer-surface is less in proportion tothe work donethaninthe cascofanyothermachineofasimilarclass. Thepulp,on leavingthe vat A andon its course to the machine-wires, flows in thedirection of the arrows, Fig. 1, over the surface R to the inclined frame S, which is perforated or covered with wire-cloth of any required degree of fineness, in passing down which the pulp parts with the surplus water,

and then falls into the breast-box T, from We are aware that it is not new to construct paper-pulp screens with a vertical jogging motion operated by means of a revolving tappet, v

and provided with a regulating wedge or wedges; and we do not broadly claim these features. V

Having now described and particularly ascertained the nature of our said invention and the manner of carryingi t into practical-effect, what we desire to claim and secure by Letters Patent is- 1. In a paper-pulp washing and straining apparatus, the combination of the vat A, verti- 0 cal standards 0, strainer-plate'frame B, vertical rods J, keys I), brackets N, hinge M, slot 0, and the tappets E, having a shaft, D, and the Wedges I, having screws 01, as and for the purposes set forth. 5 5

2. In a paper-pulp washing and straining apparatus, the continuous lubricating chamber surrounding the axle and tappets for the diminishmentof noise and-wear and tear of the machine, as described.

3. In conjunction with knotters and strainers for paper-pulp, the combination and arrangement of apparatus for extracting the surplus water after the pulp has been strained, substantially as hereinbefore described and 6 shown.

In testimony whereof we, the said FREDER- ICK WRIGLEY and J AMES ROBERTSON, have hereunto set our hands and seals this 22d day of December, 1882.
